//        根据拿到的数据去数据库查询是否有当前的用户名和密码
//        首先需要判断验证码是否输入正确,是属于逻辑关系，
//        所以一般情况会传入到service层去做
//        2.封装数据

        ProductModel productModel = new ProductModel();
        productModel.setPage(Tool.stringToInt(page));
        productModel.setLimit(Tool.stringToInt(limit));
        productModel.setName(productName);
//        3.调用逻辑层
        ProductService productService = new ProductServiceImpl();
//        4.得到返回数据
        List<ProductModel> result = productService.findAll(productModel);

        int total = productService.getCount(productModel);
//所以我们需要将结果封装成json格式的对象
// 5.返回数据到页面
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("list", result);
        jsonObject.put("total", total);
        jsonObject.put("code", 0);
        jsonObject.put("msg", "success");
        resp.getWriter().println(jsonObject);
    }
}
